Disk quotas track and control disk space usage for NTFS file system volumes, allowing administrators to control the amount of data that each user can store on a specific NTFS volume. Administrators can optionally configure the system to log an event when users are near their quota, and to deny further disk space to users who exceed their quota. Administrators can also generate reports, and use the event monitor to track quota issues.

Enforcing disk quota limits is optional. When users reach an enforced disk quota limit, the system responds as though the physical space on the volume were exhausted. When users reach an unenforced limit, their status in the Quota Entries window changes, but they can continue to write to the volume as long as physical space is available.

This tutorial will show you how to set a default disk quota limit and warning level for new users in Windows 7, Windows 8, and Windows 10.

A) In the right pane of the DiskQuota key, double click/tap on the Limit DWORD to modify it. (see screenshot below step 2)

Note

If you don't have a Limit DWORD value, then right click or press and hold on an empty space in the right pane of the DiskQuota key, click/tap on New, click/tap on DWORD (32-bit) Value, type Limit for the name, and press Enter.

B) Select (dot) Decimal, type a number (ex: "100") for how many KB, MB, GB, TB, or EB you want to set for a default quota limit, and click/tap on OK. (see screenshot below)

C) In the right pane of the DiskQuota key, double click/tap on the LimitUnits DWORD to modify it. (see screenshot below step 2)

Note

If you don't have a LimitUnits DWORD value, then right click or press and hold on an empty space in the right pane of the DiskQuota key, click/tap on New, click/tap on DWORD (32-bit) Value, type LimitUnits for the name, and press Enter.

D) Type a value (ex: "3") from the table below to have the default quota limit you set in step 4B above as KB, MB, GB, TB, PB, or EB, and click/tap on OK. (see screenshot below)

Value

Unit

1

Kilobyte (KB)

2

Megabyte (MB)

3

4

Terabyte (TB)

5

Petabytes (PB)

6

Exabytes (EB)

E) In the right pane of the DiskQuota key, double click/tap on the Threshold DWORD to modify it. (see screenshot below step 2)

Note

If you don't have a Threshold DWORD value, then right click or press and hold on an empty space in the right pane of the DiskQuota key, click/tap on New, click/tap on DWORD (32-bit) Value, type Threshold for the name, and press Enter.

F) Select (dot) Decimal, type a number (ex: "90") for how many KB, MB, GB, TB, or EB you want to set for a default warning level, and click/tap on OK. (see screenshot below)

G) In the right pane of the DiskQuota key, double click/tap on the ThresholdUnits DWORD to modify it. (see screenshot below step 2)

Note

If you don't have a ThresholdUnits DWORD value, then right click or press and hold on an empty space in the right pane of the DiskQuota key, click/tap on New, click/tap on DWORD (32-bit) Value, type ThresholdUnits for the name, and press Enter.

H) Type a value (ex: "3") from the table below to have the default warning level you set in step 4F above as KB, MB, GB, TB, PB, or EB, click/tap on OK, and go to step 6 below. (see screenshot below)
